IMPROVEM ENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 213,023, dated March 4,1879 application filed February 5, 1879.

To all whom it may concern:

Be it known that I, NILE F. VVYNKOOP, of Ohemung, Ohemun g county, NewYork, have invented Improvements in CarCouplin gs, of which thefollowing is a specification:

My invention relates to that class of carcouplings in which a slidingblock supports the pin or clamps the link against the pin, and a leveris used to elevate the latter; and my invention consists in certaindetails of construct-ion which reduce the complexity of the apparatusand permit the ready attachment and release of the pin and lever.

In the drawings, forming part of this specification, Figure l is alongitudinal section of the coupling; Fig. 2, a sectional plan, and Fig.3 an end view.

A is the draw-head, having a mouth flaring at all sides from an'oblongrecess, 00, in which slides a block, B, having a curved front edgeadapted to the end of the link 0.

A tongue, 1), extends into a contracted portion of the recess 00, andbears on a spring, D, which tends to throw the block outward, a pin, 0,extending into a groove, 0, of the block, and limiting the'movement ofthe latter.

\Vhen the pin J is elevated the block B, moving beneath, holds it inplace until the link strikes and pushes it back, when the pin will falland secure the link, as shown.

The sides of the mouth all converging toward the recess a: insure theend of the link being brought against the end of the block, fromwhatever point the link enters, and the pin being in front of the mouthof the recess, the link can be turned to any angle vertically.

In order to permit the lateral adjustment of the link, the front end ofthe block is curved, to permit the link to turn therein, and theinclined sides are carried to or back of said end, as shown in Fig. 2.This necessitates a wide block; but by providing the wide head with atongue, I), a single small spring may be used, and the cutting away ofthe draw-head, reducin g its strength, is avoided.

In order to draw the pin in a direct vertical line, the lever I ispivoted to a link, d, connected to a lug, f, at one side of the drawheadand in order to secure the pin detachably to the lever, the latter isprovided with a hooked bolt, 2', catching a staple, n, on the end of thepin, and adjustable by means of a nut,

m, to secure or detach the hook from the pin.

I do not claim the sliding block and lever; but it will be seen that bythe construction described a wide bearin g is given the block withoutcutting away the draw-head. A light spring may be used, as the weight ofthe block is reduced, while the pin is drawn vertically by simplemechanism.

The main feature, however, is the ability to adjust the link verticallyor laterally to any desired angle with the use of a sliding blockcoinciding very nearly in width and thickness with the width andthickness of the link-a result secured by carrying the flarin g sides ofthe funnel-like mouth to the rear of the center of the pin, so that thelink, while bearing on the sliding block, can be turned up, down, orlaterally until parallel with either flaring face. It will be apparentthat this result is secured without interfering with the automaticselfcoupling action of the device.

I claiml. A draw head having a block sliding against a spring in anopening nearly coinciding in width and depth with the width andthickness of the link, and with a flaring funnel-like mouth, all thesides of which meet those of said opening at the rear of the center ofthe pin, as set forth.

2. The combination of the draw-head, link, pivoted at one side of thehead, lever I, pivoted to the link, and adjustable hoolcbolt i, carriedby the lever and adapted to a staple, n, at the end of the pin, as setforth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
